How do you want to revise this topic today?
Read & Recall
You will begin by reading the information sheet carefully to build your understanding of the topic. This matters because learning is strengthened when you make your brain work to remember information rather than just re-reading it. Finally, you will check to identify anything you missed or misunderstood, helping you correct and improve your knowledge.

You will start by watching or listening to an explanation to help you understand the topic. You will then recall what you can remember. This step is important because trying to remember from memory strengthens learning and highlights what you do and do not yet know. You will then complete tasks to check accuracy, fill gaps, and improve your understanding.

Close the sheet. Write down everything you remember. 5 min✓
This is the most important step. Do not skip it.
▾
Do this exactly, in this order
This is called Look → Cover → Recall → Check. The uncomfortable feeling of not being able to remember is your memory being strengthened — not a sign you're bad at this.
①
Close the information sheet. Do not look at it.
②
Get a blank piece of paper. Write everything you can remember — headings, facts, definitions, anything.
③
When you get stuck, keep trying. Do not open the sheet yet. Push through for at least 3 minutes.
④
Now open the sheet and check. Circle everything you missed. These are your gaps.

Answer these questions — say your answers out loud 3 min✓
You don't need to write anything. Just speak your answer.
▾
What to do
Read each question, then say your answer out loud. If you have no idea, say "not sure" and move on. This warms up your memory before you hear the content.
Question 1 of 3 — say your answer out loud
What is a bit?
Question 2 of 3 — say your answer out loud
How many bits are in a byte?
Question 3 of 3 — say your answer out loud
Put these units in order from smallest to largest: gigabyte, kilobyte, megabyte, terabyte.
Don't worry about being right — you're about to hear all of this.
🎧
Listen to the podcast ~10 min✓
Listen with headphones. Full attention — this is your main way of learning the content.
▾
How to listen — this is not background music
Headphones on. Phone face-down. Just listen for the full duration. As you hear each topic, try to picture it. Sit for 30 seconds at the end and think about what you heard.
🎬
Watch the video — with the information sheet open beside it ~7 min✓
Use the sheet as a visual anchor — find each topic as you hear it mentioned.
▾
What to do
Open the information sheet alongside the video. As each topic is covered, find it on the sheet and look at it — the diagram, the colour section, the key words. You're pairing what you hear with what you see. If something doesn't make sense, ask the AI tutor.
🗣️
Close everything. Say or draw what you remember. 5 min✓
This is the most important step. You do not need to write a single word.
▾
Do one of these — pick whichever feels right
Speaking and drawing work just as well as writing. The point is to retrieve from memory — not to copy from somewhere.
①
Close everything first. No sheet, no video, no podcast.
②
Talk it out. Explain the topic out loud as if teaching it. Record yourself if that helps.
③
Or draw it out. Sketch a diagram from memory. No labels needed — just from memory.
④
Now check. Open the information sheet. What did you miss? Look at those gaps for 60 seconds.
